i IMPROVEMENT IN FARM-GATES.

The` Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom 'it mwy concern:

Be it known that I, THOMAS F. HALL, of Circleville, in the 'county ofPickaway, and State of Ohio, 'have invented new and useful' Improvementsin Farm- Gates and I do hereby. declare that the following is a full andexact description of the same, reference being had tothe accompanyingdrawings, making part of this specification, in which- Figure l is afront elevation;

Figure 2 is a top view; and

Figure 3 is a section on line x of iig. 2, showing how the gate is heldsuspended by the springs H H.

Like letters refer to like parts.

My invention relates to that class of farm-gates that will rise and fallvertically between two posts, and while up for the passage of vehicles,is partially sustained by weights'.

In the drawing- A represents the posts, and

B, the braces.

The posts may be set in the ground in the usual manner, or framed into asill.

The tops of the posts are connected by a double arch-way, C C, havingsufficient space between them, shown in tig. 2, to allow the thicknessof the gate to pass between them.

At the centre of this arch the pulleys D D are mounted, as shown, andfor purposes hereinafter described.

There are also two other pulleys, YE E, located, respectively, near thetop and in the vertical centre of each post. r

The gate is shown at F, and may be made of horizontal barsand verticalslats, or in any other convenient style. The ends'are tted to run ingrooves,'or guide-ways upon the inner surface ofeach post.A

A catch, G, of any convenient form, is placed upon the top of the gate,and secured near the middle; and this catch, when the gate is raised, ashereinafter described, eug`ages between twov springs, H H, which aresituated between the pulleys at the top of the arch.

H' H' are springs,-which are secured to arched pieces O O, and soarranged as to bear upon the springs H H, near the points-where theygrasp the clutch G, so they may insure the holdingof the gate in itsposition bythe springs H H until it is released by pulling the cord L.

The weights that partially balance the gate are shown at I I. From each'of these a cord passes over the pulley E, and is attached tothe 4lowercorner of the gate, respectively, as shown.

The pulleys D D carry each being attached to the middle of the gate,

a cord, K, one end and the other end to a-post convenient to theapproach of the gate from each direction. y

By pulling upon either of these ropes, the gate will be raised, asshowuat F', in fig. 1, and carried up until the catch G engages with thesprings H H, where it is held until released.V This is accomplished bymeans oi ropes, or cords, L L, o ne end of which is attached to thesprings H H, and the other to a postconvenient to the place of exit.v Bypulling upon either of these ropes, the catch Gr is released from thesprings H H, and the gate descends by its own gravity, which should be alittle greater than that of the weights, thereby giving it an easy andregular movement.

What I claim as my invention and improvement, and desire to secure byLetters Patent, is

1. The posts A, in combination with the arch O and pulleys D and E, asspecified.

2. The combination of the gate F with the posts A, arch C, aud pulleys DE, as speciiied. 3. The combination of the catch springs H, as setforth.

4. In-combination with the elements of these preceding clauses, theropes K and L, and weight I, as speciiied. l 5. The arrangement of thesprings H H, for the purpose specified.

In testimony whereof, I have signed my' name to this specification, inthe presence of two subscribing witnesses..

THOMAS F. HALL.
